Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Qyrr – simply and modern QR-Code creation plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the blob_to_file() function in all versions up to, and including, 2.0.7. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Qyrr WordPress plugin has an arbitrary file upload vulnerability in the blob_to_file() function. Authenticated users with Contributor-level access or higher can upload arbitrary files to the server due to missing file type validation, potentially achieving remote code execution.

MitigationUpdate the plugin to the latest version which should contain proper file type validation, or disable the plugin until a patch is available. If the plugin cannot be updated, consider restricting user permissions or removing the plugin.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Qyrr plugin is installed
    Check if the /wp-content/plugins/qyrr/ directory exists on the WordPress server
    Affected if The plugin directory exists on the server
  2. Identify plugin version
    Open the main plugin file (e.g., qyrr.php) in /wp-content/plugins/qyrr/ and locate the version comment or header
    Affected if Unable to determine version or version is older than the patched release
  3. Confirm vulnerable function exists
    Search the plugin source code for the blob_to_file() function
    Affected if The blob_to_file() function is present in the plugin code
  4. Check for file upload endpoint
    Search plugin files for code handling file uploads or blob data processing
    Affected if File upload handling code is found without proper validation checks
  5. Audit user roles with upload access
    In WordPress admin, review users with Contributor, Author, Editor, or Administrator roles who can access the vulnerable functionality
    Affected if Any user with Contributor-level access or higher exists on the site

If the Qyrr plugin is installed, contains the blob_to_file() function, and has users with Contributor-level access or higher, the environment is likely affected by this arbitrary file upload vulnerability.
